' FLUID MIXER.

Specification of Letters Patent.

Patented May 30, 1922.

Application filed May 9, 1921. Serial No. 467,804.

To (/77 llllOl/l. if may con ern:

Be it known that I. Hizxni G. LEvY. a citizen of the I'nited States. and a resident of the city and county of San Francisco. State of ('alifornia. have made a new and useful invention--to wit, Improvements in Fluid Mixers: and I do hcrcb declare the following to be a full. clcar. concise and exact description of the same.

This invention relates pHl'llClllHl'ly to llnid mixers.

An object of this invention is to provide an electrically operated lluid mixer for use. at drink mixing dispensers which will be superior in point of simplicity and inexpensiveness of construction. positiveness of operation. facility and convenience in use. and general eliiciency as contrasted with any device of a similar nature. Other objects and advantages will appear as this description progresses.

In this specification and the annexed drawings. the invention is illustrated in the form considered to he the best. but it is to be understood that the invention is not limited to such form. because it may be embodied in other forms. and it is also to be understood that in and by the claims following the description. it is desired to cover the invention in whatsoever form it may be embodied.

In the accompan \-'ing two-sheets of drawings.

Figure. 1 represents a front elevation of a drink mixing device mounted on a supporting pedestal. V

Figure 2 represents a side elevation of Figure 1.

Figure 3 represents a modified side view of Figure 1.

Figure 4 represents a plan view through Figure 1 on the line 4--L In detail the construction illustrated in the drawings comprises a hollow standard 1 or other equivalent supporting medium. the end thereof flaring into a base 2. adapted to rest upon either a counter or marble 3. Where the complete mixer maintains a semipermancnt position, it is desirable that the base 2 of the standard 1 be provided with an extended lip 4 through which a. clamping screw 5 or other e( uivalent means may he passed for frictionally engaging the counter or other element upon which the standard 1 is mounted. The opposit end 6 of the standard 1 terminates in a saddle.- l ike fastening to which an electrically oper of the standard so that the commutator" shaft is disposed substantially parallel with thc axis of the standard 1. suitable agitalor or mixer shall 9 is secured on the end of the. connnutator shaft by means of the coupling 10 or other equivalent media.

A platform for supporting a fluid eontainer. comprising a flat shelf portion 11 having a peripheral rim 12 therearound and provided with spaced rearwardly extending projections or arms 13 and 14 thereon is pivoted by the shaft '15 to an integral projection 16 formed on the standard 1. This construction is clearly shown in Figure 4 where the spaced outwardly flaring arms 13 and 14 extend on opposite sides of the standard so as to permit the weighted ends of said projections passing on each side of the standard. The arms 13 and 14 increase in cross section from the junction point to the heavily weighted ends. which serve as counter-halances tending to normally elevate llie shelf portion 11. Integral lugs 17 and 18 are formed on opposite undersides of theprojection 11' and act as stops to prevent any downward movement of the weighted arms 13 and 14. Thus it is possible to depress the shell portion of the platform about. its pivot point 15 at the. same time elevating the counter-halances 13 and 14. so that upon releasing the downwardly moving force from the shelf portion. the weighted arms through gravity will move back into a normal position. substantially at right angles to either of the axes of the agitator 2) or standard 1.

This invention operates as follows:

fluid compound to be agitated or a beverage to be mixed would be placed in asuitahle container or vessel 20 and which would be grasped by one hand of the attendant. lVith the other hand, the attendant would depress the shelf of the platform 11 so that the throat of the container could he passed within the space 23 between the separated ends of the rim 12 and also within the space 24 between the separated rim ends at the. point substantially diametrically opposite. the front opening 23 aforementioned,

to permit the glass or container being passed around the agitator 9. After the, container tive to the agitator, the operator would permit the plat form or shelf to be elevated so that the glass or container could rest thereon substantially as shown in Figures 1 and 2. At the completion of this operation. one of the fingers of the operator would be extended to operate the control switch 25 through.

suitable current carrying conduits connecting a source of energy with the motor (3. starting it in operation.

It will be noticed that the axis of the agitator shaft is positioned eccentrically to the axis of the pivot platform and container so that when the agitator shaft is started rotating, it will completely swirl and internnx the ingredients. In standard practice where the agitator shaft is placed concentric-ally with the axis of the fluid container, the effect of the rotary Inotion and centrifugal action is to throw all of the ingredients away from and out of contact with the agitator shaft, whereas the eccentric arrangement of the agitator shaft and drink container has proven a very eflicient means for obtaining a frothy and creamy mixture.

Having thus described my invention. what I claim and desire to secure by Letters Patent is: V

1. A device such as described, comprising in combination a standard; a motor fixed thereon and having an agitator projectin therefrom: and a platform pivotally moun ed on said standard and having counterbal ance arms extending on both sides of said standard.

2. A device such as described. comprising in combination a standard; a motor fixed thereon and having an agitator projecting therefrom; a platform pivotally mounted on said standard and having counterbalance arms extending on both sides of said standard; and means on said standard for engaging said plat form to hold it at substantially right angles to the vertical axis of said standard.

3. A device such as described. comprising in combination a standard: a. motor fixed thereon and having an agitator projecting therefrom: a platforn'i pivotally mounted on the front side of said standard. adjacent said agitator. having connterbalance arms thereon extending rearwardlyon both sides of said standard. adapted to maintain said platform substantially at right angles to the axis of said agitator; and a. rim around said platform having a gap through the front partthereof.

-t. A device such as described comprising in combination a-standard. a motor on said standard having an agitator projecting therefrom. a platform. pivotally mounted on said standard. and having counlerbalance arms extending on both sides of said stand ard to maintain it at substantially right angles to the axis of said standard and means on said plat form for positioning a container ccccntrically to the axis of said agitator.

A device such as described comprising in combination a standard: a motor on said standard having an agitator projecting therefrom: a platform. pivotally mounted on said standard, and having counterlmlance arms extending on both sides of said standa rd to maintain it at substantially right angles to the axis of said standard: means on said platform for positioning a container eccentrically to the axis of said agitator and a motor control switch on said standard adj accnt the pivoted platform.

In testimony whereof. I have hereunto set my hand at San Francisco. California. this 30th day of April 1921.
